Is the temperature on the Qinghai-Tibet line suitable for cycling in June?

June is the peak season for cycling. Summer has come, the weather has become a little warmer and the temperature is right. If you are lucky in June, you can meet Tibetan antelopes in Hoh Xil. However, it is suggested that the best riding time is from July to mid-August. The Snowton Festival (June 30th in Tibetan calendar) and the Horse Racing Festival (June, July and August in Tibetan calendar) are relatively big festivals that can be caught up in this period. You can arrange your itinerary according to the Tibetan calendar. After August 20th, the section from Kunlun Mountain to Lhasa will often encounter snowstorms.

1.cycling temperature of Qinghai-Tibet line in June:

1. elevation, the average elevation of the whole Qinghai-Tibet line is over 4000m, the lowest point is 2840m above sea level in Golmud, and the highest point is 523 1 m at Tanggula Pass, where it may snow.

2. Rain and snow, the higher the altitude, the closer it is to the mountain pass, and the easier it is to encounter rain and snow. Generally, when it rains (snows), people will wear more clothes, which will affect riding. When you ride a bike in a raincoat, the wind resistance will also increase. In addition, when it rains (snows), the temperature drops greatly, which seriously affects your riding state. In the north of Tanggula Mountain, the air is particularly dry because of the blocking effect of Tanggula Mountain. In the south of Tanggula Mountain, due to the warm and humid airflow in the Indian Ocean, basically, you will have a heavy rain inadvertently.

3. At high altitude, with the increase of altitude, the oxygen content in the air gradually decreases, and cycling, an oxygen-consuming exercise, needs more oxygen, so sometimes I feel that I can't breathe well. At this time, you must pay attention to adjusting your breathing, otherwise you will feel chest tightness for a long time and easily cause altitude sickness.

4. Sunshine, the air on the plateau is thin and the ultraviolet rays are particularly strong, so special attention should be paid to sun protection. If the skin is exposed to the sun for a long time, it won't take long to get sunburned.

5. Physical strength, which is most closely related to individuals except external factors. Everyone has different physical strength, different speed, different endurance and different performance when riding. So there are strategies written by different people, but the main reason is that they have different views on road conditions and riding. Therefore, when arranging your trip, you must consider your physical strength, make reasonable arrangements, and never try to be brave.

2. Road conditions of the Qinghai-Tibet Railway: The Qinghai-Tibet Railway is probably the best of the four routes into Tibet, basically with asphalt pavement and two lanes. Since the opening of the Qinghai-Tibet Railway, there have been relatively few cars on the highway, but the safety still cannot be relaxed.

On the expressway near1200km, the following sections are in poor condition:

(1) After 20 kilometers of Xidatan, several kilometers of pavement are all cement pavement, which is crushed by traffic and uneven;

(2) The pavement in the first few kilometers of Wudaoliang is also a cement pavement, and because it is downhill, there are many pits, and the speed is often unstable if it is too fast;

(3) Near Tanggula Pass, the first few kilometers from Tanggula Pass to Toudaoban are all red clay roads, which are rugged and dusty.

3. Hyperreflexia: In an anoxic environment, due to insufficient oxygen supply to various organs of the human body, respiratory system, circulatory system, hematopoietic system, nervous system, digestive system, etc. Everyone has to work twice to adapt to the influence of insufficient oxygen on the body. In this case, a series of reactions often occur: shortness of breath, pause, drowsiness or insomnia, polyuria or oliguria, headache, dizziness, vomiting and other symptoms, which are called altitude sickness.

High counter-defense:

1. If you want to stay on the plateau for a long time, don't go from low altitude to high altitude quickly. Theoretically, the rising height should be 300-500 meters every day. Don't enter too high an area. At the height of 5400-5800 meters, Tibetans will also have some reactions, not to mention plain people.

2, do not exercise excessively, do not exercise vigorously: when entering the plateau, you must combine work and rest and have a good rest. Excessive exercise and strenuous exercise will only aggravate the appearance of altitude sickness.

3, pay attention to diet: drink plenty of water, if possible, drink more hot water to adapt to local food, such as butter tea. And eat more foods with high carbohydrate, high sugar, high-dimensional C and high protein.

4. Spare supplies: you can spare oxygen bottles and rhodiola. However, these will only relieve the symptoms, not cure them. If severe altitude sickness occurs, it should be transferred to low altitude areas as soon as possible for adaptive recovery or treatment. In addition, the extract of Rhodiola sachalinensis, a plateau plant, is not suitable for long-term use.

5. Tips: Headache is the most common reaction after arriving at the plateau. If you have a headache, tying your head tightly with a cloth belt will relieve the symptoms. If vomiting occurs, drink some hot water, but don't drink cold water. Drinking cold water often causes more serious vomiting.
